SINGLE SPEED & BMX
Includes 16" and 20" BMX Bikes
Assembly is the same for boy’s and girl’s bikes.
Getting Started
Open the carton from the top and remove the bicycle. Remove the
straps and protective wrapping from the bicycle. Inspect the bicycle and
all accessories and parts for possible shortages. It is recommended that
the threads and all moving parts in the parts package be lubricated prior to
installation. Do not discard packing materials until assembly is complete
to insure that no required parts are accidentally discarded. Assemble
your bicycle following the steps that pertain to your model.
Note: Your bicycle may be equipped with different style components
than the ones illustrated.
Handlebars
Remove the protective cap from the stem wedge and loosen the stem
bolt using the 6mm Allen key. Some models may use a 13mm
hexagonal bolt instead of an Allen key bolt. Place the handlebar stem
into the head tube, observing the minimum insertion mark on the
handlebar stem and ensuring that all cables are free of tangles. Check
that the fork and the handlebar are facing forward, and that they are
properly aligned with the front wheel. Tighten the stem bolt. Rotate the
handlebar to the desired position and tighten the Stem Cap Binder Bolts
securely using a 5mm Allen key. You must alternate tightening each bolt
until all bolts are secured and the stem plate evenly clamps the handlebar.
The handlebar must be inserted so that the minimum insertion
mark cannot be seen.
Warning: Over tightening the stem bolt or headset assembly may
cause damage to the bicycle and/or injury to the rider.
